It uses a water/pulverized organics (wood, plastic, tires, computers, plastic, sewage sludge, etc) as feedstock, which is cooked at about 500 F and then flash cooled so that the oil separates. The gases given off are recycled to heat the slurry mix. As the solids are separated from the oils, there is carbon, metals, and fertilizer and light oil streams so that all is recovered.
